In carrying fout" the invention as applied to the constructionof ballbearings, Figs. 1 t0 7 inclusive, the twoballr-aces are made of stampedsheet metal discs 1,2, each hav'ing an annularch'an'nel 3which may be ofcurved section'as' shown or of Vj-section. These annular channels may-beformed in the discs or rings by the operation/of press tools As shown"in Fig. 7 two such discs or-rings are provided for each bearing",the-channels 3 engaging opposite sides of the balls of the ball 1 race,the diameter of the balls i and the form of the plates 1',- Q 'beingsuch that the latter do not contact when assembledto form a hearing. Theball cage or frame, Figs; 5 and 6, is made up 01 two similarsheet metalrings 5 in which arejstamped a number of holes corresponding to thenumber of balls t to be h eused, the holes being 'formed with shortflanges'fi preferably inclined to the plane ef'the ring," the flangesthus; forming'shallow conical dishf ings '(see Fig. 6) stampedont'froni'themetal of the rings; Two such rings reversed are placedtogether to enclose the ballsand re- 'tain'them in position in the ringcage, the coii- 'ical flanges 6 aroundthe apertures forming a housingwhichsecurely holds the ball in position the latter projecting-wellabove each e5 figure being insection and the right hand- I .edge oftheflanges of the ring cage. The

rings may be secured together by riveting, eyeleting, or as shown byforming lubs or projectlons 7 on" one ring which are bent over theadjoining edge of the other ring. 'In Figs. 5a and 6a I have. showntheouter peripheral edge f of one disc, turned around the'edge of theother, and also the inner peripheral edge 6 of the same ringelementturned about and engaging the cor respondinginner edge'o-f theother, thereby forming a firm and rigid connection between them. A ballring cage constructed as 'de-.

I scribed is then inserted between the two ana nularly channelled discsor ringsto form a complete ball bearing. Such a ballbearing is ofconsiderableadvantage in thebuilding' up of .constructional models frominterthe bearing is assembled more or less encloses theballs, vFig. 7.The race discs ofthe ball bearing .may be perforated withfholesj 1Ospaced apart at some standard pitchand/or slots 11 to enablesuchelements-readily to be connected up to other parts of a toybuildingoutfit by bolts and nuts and so built in to the models to beconstructed. 1 r j 5 l a For use inthe heavierclass of modelwhere it isdesirable to have roller instead of ball bearings, the race discsla,Figs.

instead of being stamped with an annular channel are preferably providednear the periphery with a peripheral edging 12 parallel to but raisedabove the plane of the disc or ring, an annularshoulder 13 being thusformed around each disc, the edge12 and the shoulder 13 thus forming therace-way ,for the rollers. The roller cage or frame con- .sists of aring 14, Figs. 10 and 11, of'angled section the rollers 15 beingpiv'otally carried on the peripheral flange lta of this ring.Preferably; the; rollers are mounted upon studs 16 which pass throughbosses 17 on the rollers and aresecured by nuts 18 to the angle sectionring, the bolts or studs being radially disposed to, the roller frame.Thenrollers are preferably flanged at 19 on oneside of their tread, thetread 'of the roller-running on the raised peripheral edge, 12 of therace disc and the flange engaging the shoulder 13. As

1in thecaseof. the ball race the discs ;1a may beformed with slots 11and" circular holes 10 spaced apart at some standard pitch to en abletheelementsto be connected up interch angeably to other parts of the toyoutfit and. nneor both of the race discs may be toothedon its peripheryas shown at; 20, Fig- 8, to enable it to bedriv'en by a sprocket chainor pinion 21'engaging therewith. The roller frame may be'furthercentralised 1n the bearing by fitting a perforated strip 22diametrically'across the frame, the central perforation of the stripengaging theusual ialrod 3 w ic p sses h ough h two discs and theintervening roller frame when assembled to form a unit, as shown in Fig.

7 12. This latter form of-roller bearing is suitable for buildingup' theheavier type of constructional toy for use in demo'nstration model's forshop windows or the like'sltuations.
